Great idea..Slightly flawed execution
PROS:
Great story Some moving/awesome moments
Brilliant multiplayer maps
Easy controls
4 difficulty levels
Quite a lot of variation, but not so much that it feels silly (Black Ops?? =P)
CONS:
Pretty short story
Not many guns (but lots of mods for them)
Server was down.. but is ok now =)
Some minor annoyances in campaign
Don't buy used or you have to buy a 800 Microsoft Point code to go past level 5 online (see below)
Just don't see it as a direct COD rival, and you should love it. even if you like COD and Battlefield, just give Homefront a few hours and it gets better and better!
To be honest, the first 2 missions don't allow much exploration, but as an intro to the game they work OK. Don't believe the user reviews that give it less than 4: even if you don't enjoy the game, theres no way it's that bad!! A good game, but don't necessarilly buy it right now. Wait till it's a little cheaper, but remember if you buy used you have to purchase a code to get past level 5/75 on multiplayer, for 800 Microsoft Points. Before level 5, not all game modes and few guns are unlocked, so be warned.
Hope I helped =D
